Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a connected fume pipe capable of early construction of a fume pipe at a construction site and a method for suspending the same.

[Conventional technology]

 Conventionally, the fume pipe and the steel collar or the concrete collar and the rubber ring for waterproofing are carried in separately, and they are lifted one by one at the construction site, and they are installed at predetermined positions by repeating the suspension. ..

 Further, as shown in FIG. 7, in the construction, the fume pipes H are arranged one by one using the centering wire rope 9 and the wire rope 10 and adjusting the position with the lever block.

[Problems to be solved by the invention]

 The recent situation at the construction site is that the aging of construction workers and the shortage of manpower are serious problems, and there is a need for more efficient construction of fume pipes.

 In order to improve the efficiency of construction, it is possible to increase the length of one pipe from the current 2m to 2.43m to 5m to 10m. The number of hangings of the building will be reduced, and the efficiency of construction will be improved. As a method of promoting this lengthening, there is a method of manufacturing one tube by integral molding, but in this method, since the existing equipment is compatible with a length of 2 m to 2.43 m, it is significantly Equipment investment is required.

 In addition, if the construction location is a location that is subjected to an eccentric load such as live load in the axial direction of the pipe or is on soft ground, the longer the pipe length, the greater the bending force that will be applied. Therefore, there is a problem in that it is necessary to reinforce the pipe in the axial direction.

 On the other hand, another method of increasing the length is to join the tubes of the current length. With this method, existing equipment can be used as is, and it is much more economical than the former method. Furthermore, when joining this method, there are methods of joining the tubes with a PC steel rod, and methods of using an adhesive with high steel property after hardening. As in the former case, there is a problem that a large bending force acts in the axial direction of the pipe depending on the place of use, and reinforcement is required to cope with this bending force as in the former case.

 Therefore, in order to solve such a problem, it is necessary to increase the length of the pipe and to provide one elongated pipe with appropriate flexibility. It turns out that.

 Now, when actually constructing such a flexible pipe, it is necessary to carry out the lifting work safely and efficiently. As a method of this, it is inevitable to use a method in which a plurality of connected pipes are individually suspended as shown in Fig. 8, but this poses a problem in terms of construction efficiency.

 Therefore, if multiple pipes are connected and a flexible connecting pipe is suspended at two points in consideration of safety, the stability differs depending on the position where the wire is fixed. That is, as shown in FIG. 5, if the distance between points A and B is too short, the tubes at both ends will have an upward arcuate shape.

 In addition, as shown in FIG. 7, if the distance between points A and B is short, there is a problem in that a downward bow is formed and the balance becomes unbalanced.

 Therefore, the present invention was devised in view of the problems of the above-mentioned conventional techniques, and in the manufacturing stage, a plurality of short fume pipes are preliminarily joined to each other in a flexible state. The purpose of the present invention is to provide a connected fume pipe that can be efficiently suspended while having the flexibility to disperse the bending force in the pipe axial direction while enabling early construction of the fume pipe.

[Means for solving the problem]

 In order to achieve the above object, in the connected fume pipe according to the present invention, a joint portion is formed at the pipe ends of the leading pipe and the succeeding pipe, and the joint portion of the pipe is bonded with an adhesive having elasticity or a rubber ring. It is arranged and the joints of each pipe are connected with a collar to form a single fume pipe.

 In addition, the connecting fume pipe is a hanger that can fix the wire at a position of 1/3 to 1/4 from the end of the joint pipe between the leading pipe and the pipe next to the last pipe when the fume pipe is suspended by the wire. It is configured with.

[Action]

 The joint between the leading pipe and the succeeding pipe and the collar are bonded together by an elastic adhesive to form a single fume pipe. After placing a rubber ring at the joint of each tube, the collar is attached from the outside to form a single Hume tube.

 Further, when suspending the connected Hume pipe with a wire, the wire is fixed and hung from the joint pipe ends of the leading pipe and the tail pipe at 1/3 to 1/4 positions.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

 1 to 4, the Hume tube according to the present invention is formed by joining a plurality of fume tubes 1 and 2 into one connected fume tube.

 That is, the joint portion 4 is formed at the pipe ends of the leading pipe 1 and the succeeding pipe 2.

 When connecting the joints 4 of the pipes 1 and 2 with the collar 3, as shown in FIG. 2, the joint 4 or the inner surface of the collar 3 is coated with an elastic adhesive such as urethane resin. Then, as shown in FIG. 3, a groove 7 is cut in the joint 4 and a rubber ring 8 is arranged in the groove 7, and the joints 4 of the respective pipes are connected by a collar 3. Formed into a single fume tube.

 In the case where the joint 4 and the collar 3 are connected by adhering with an adhesive 6, they are applied to a place where a large bending force does not act in the pipe axis direction, such as a relatively stable place on the ground.

 In addition, when the rubber ring 8 is placed between the joint 4 and the collar 3, a large bend is made in the pipe axis direction, such as in the ground other than this, especially in a place where there is a risk of uneven settlement after the construction. It is applied to the place where the force of.

 Further, the rubber ring 8 having a slightly high hardness is used, and one or more rubber rings 8 may be arranged in the joint portion 4.

 Further, when a plurality of rubber rings 8 are arranged in the joining portion 4 or when a wide one is used, the connecting pipes can be kept horizontal, and the resistance force of the pipes coming out becomes large.

 The method of suspending the connected fume pipe is as follows. When suspending the above-mentioned fume pipe with a wire, fix the wire A at a position of 1/3 to 1/4 from the joint pipe end of the front pipe 1 and the rearmost tail pipe 2. Be seen.

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects.

 In the past, the connection of short fume pipes was repeatedly performed at the construction site, but by forming multiple short fume pipes into a single long fume pipe. , Construction work is now several times faster.

 In addition, since the wire is hung up with fixed wire at the position of 1/3 to 1/4 from the end of the pipe where the leading pipe and the adjacent pipe of the tail pipe adjoin, the pipe is lifted as shown in Fig. 5 and Fig. 6. Alternatively, it can be lifted in a horizontal balance as a single pipe as shown in Fig. 4 from the state of being bowed downward.

 Further, since the joints of the individually connected pipes are flexible, the bending force in the pipe axial direction can be absorbed at the joints. As a result, even though it is a long pipe, it does not exert excessive force on the pipe body, and it is possible to deal with it in places where uneven settlement occurs partially.
